Process and related plant for producing steel strips with solution of continuity

A process for the manufacturing of steel strips, comprising:

• continuously casting thin slabs having thickness of between 45 and 110 mm and a high mass flow, which is defined as an amount of steel passing in a time unit at an outlet of the continuous casting, wherein liquid core reduction is performed during continuous casting of the slabs;
• shearing the slabs directly following the continuous casting where the liquid core reduction has been performed and prior to any rolling;
• heating the slabs;
• rolling the slabs through a finishing rolling mill, which has multiple stands for rolling,
• wherein the heating is obtained, at least partially, by induction heating with a working frequency sufficiently low to bring the heating to a core of the slabs and to substantially maintain a same temperature difference between an inside and an outside of the slabs up to entry of the slabs into the finishing rolling mill, and
• whereby an average temperature in any transverse cross-section of the slabs is higher than a surface temperature of the slabs, the temperature being equal to or higher than about 1100° C., and at the core of the slabs, the temperature being at least 100° C. higher than the surface temperature.
